MechaCat02 1eebb90e25 fix(crawler): unhang shutdown on lingering Arc<Browser>, silence WS noise (0.43.1) ...

- Handle::close aborts its chromiumoxide driver task when another
  Arc<Browser> outlives the call, so shutdown returns instead of
  hanging on a stream that never terminates. Generic close_or_abort
  helper with regression tests covering both Arc paths.
- daemon.shutdown() is wrapped in a 5s timeout in main as defense
  in depth.
- Default RUST_LOG silences chromiumoxide::conn / chromiumoxide::handler
  WS-deserialize ERROR spam.
